[Dovecot] Configuring TLS 1.2
by Phillip Odam 25 Jun '13

25 Jun '13

Hi I'm running dovecot 2.1.6 and am trying to configure it to require TLS 1.2. So far I've only got as far as getting TLS 1.0 going. In the config file <dovecot root>/etc/dovecot/conf.d/10-ssl.conf, I've tried setting ssl_protocols to values like TLSv1.2:!TLSv1:!SSL3 but without any success. Attempts to google this matter turns up results for dovecot v1.2 as opposed to configuring TLS 1.2 in dovecot And having a look over the mailing list archive hasn't turned anything up thus far. Any pointers would be greatly appreciated. Thanks Phillip

[Dovecot] Sieve file permission problem
by Zoltan Lippai 25 Jun '13

25 Jun '13

Hi folks, I am using dovecot 2.1.7 with the ManageSieve plugin which works great. Recently I set up Afterlogic webmail on my server (the community version) and it has a nice UI to manage the sieve settings. It uses port 2000 to communicate with dovecot via the ManageSieve plugin. Also, dovecot uses Maildirs to store the messages. The problem is that the permissions on the files that store the sieve rules are to strict. I am talking about the "sieve" directory and the .dovecot.sieve file. The sieve folder has a chmod 700 and the .dovecot.sieve is chmod 600. Both are owned by vmail:mail If I delete these two items, then the rules can be saved via the web interface. Then these files are created but for some reason the ManageSieve plugin can't modify them. Here is the output of dovecot -n: http://pastebin.com/4eqyBKCA Can you help me out on this? Thanks a lot! Zoltan

[Dovecot] Quota based on LDAP group
by Pavel Herrmann 25 Jun '13

25 Jun '13

Hi I have a setup where my dovecot (2.0, if that makes a difference) authenticates against an LDAP directory. In my scenario, I have two types of users, lets call them "normal" and "privileged". What I need is for the normal user to have a fixed quota, but for the priviledged to have none. (The users do not exist on the underlying system, so I cant do quota based on FS) The issue is that my LDAP is actually an AD, and there is a fair amount of new accounts over the time (in other words, I cannot use LDAP attribute for storing quota, because the AD tools don't understand it, and I would have to add it manually for each new account). The approach I had in mind is using quota based on user group (I do have groups representing both normal and priviledged users), but I cannot find a way to set it up in dovecot. Am I missing something or does dovecot not support LDAP groups as attribute source? thanks Pavel Herrmann

[Dovecot] auth probes without IP - "Initial status notification not received ..."
by LEVAI Daniel 25 Jun '13

Hi! I've been getting a bunch of these messages lately in my logs: dovecot: master: Error: service(auth): Initial status notification not received in 30 seconds, killing the process dovecot: auth: Fatal: master: service(auth): child 11016 killed with signal 9 dovecot: master: Error: service(auth): Initial status notification not received in 30 seconds, killing the process dovecot: auth: Fatal: master: service(auth): child 27660 killed with signal 9 # fgrep -c -e "master: Error: service(auth): Initial status" dovecot.log* [...] dovecot.log.1:501 dovecot.log.2:250 [...] But I can not link these auth probes to any IP addresses within the dovecot log files.

[Dovecot] Warning recipient when message delivery fails due to over-quota
by Ben Johnson 24 Jun '13

24 Jun '13

I'm working to configure automated quota notifications in Dovecot and am wondering if it is possible to send a warning message to a user when message delivery fails because the user is over-quota. I already have the following directives configured: quota_warning = storage=95%% quota-warning 95 %u %d quota_warning2 = storage=80%% quota-warning 80 %u %d quota_warning3 = -storage=100%% quota-below below %u %d These seem to function as expected, but the problem I'm facing is that when a message is large enough to take the user's quota from, say, 84% to over 100%, the message is rejected (as expected), but the user is never warned that a message failed to be delivered because it would have put him over 100% usage. I suppose that I'm looking for a trigger that is tripped when delivering the message *would* put the user over-quota (as opposed to *does in fact* put the user over). The sender receives an automated rejection message already. I'm wondering if the recipient can be warned at the same time. (I'm not concerned about further increasing the user's quota consumption with the warning message; I would set noenforcing to 1.) Is this possible? Any help is much appreciated. Thanks in advance. -Ben

[Dovecot] mail_max_userip_connections on a per user basis

Hello, Can the above setting be applied on a per user account basis? I thought that maybe something like per account quotas might be a possible method but not sure. Thanks.
